S390: Support guarded-storage core note sections
Newer Linux kernel versions offer two new register sets in support of the
z/Architecture's guarded storage facility: NT_S390_GS_CB, the
"guarded-storage registers", and NT_S390_GS_BC, the "guarded-storage
broadcast control block". This patch adds support for the respective core
notes sections to binutils.
bfd/ChangeLog:
* elf-bfd.h (elfcore_write_s390_gs_cb): Add prototype.
(elfcore_write_s390_gs_bc): Likewise.
* elf.c (elfcore_grok_s390_gs_cb): New function.
(elfcore_grok_s390_gs_bc): New function.
(elfcore_grok_note): Call them.
(elfcore_write_s390_gs_cb): New function.
(elfcore_write_s390_gs_bc): New function.
(elfcore_write_register_note): Call them.
binutils/ChangeLog:
* readelf.c (get_note_type): Add NT_S390_GS_CB and NT_S390_GS_BC.
include/ChangeLog:
* elf/common.h (NT_S390_GS_CB): New macro.
(NT_S390_GS_BC): Likewise.
